If an atom has 52 protons, 63 neutrons, and 54 electrons, what is the overall mass of this atom (in amu)? What is the speed (in terms of c) of a proton if its mass is twice its rest mass? A proton has mass of 1.7 x 10^{-27} kg. If the proton's speed is...
Prior to 1961, a unit of atomic weight was based on 1/16th (0.0625) of the weight of an oxygen atom. After this point, the standard was changed to be 1/12th the weight of a carbon-12 atom in its ground state. A carbon-12 atom is assigned 12 atomic mass units. The unit is dime...
B. Atomic weight is determined by the number of protons in an atom of a given element. C. The reactivity of an atom is based on the nu If an atom has 1 proton, no neutrons, and 1 electron, what element is it, what is its mass, and what is its charge? A) Hydrogen, 1 amu, ...
they are found in. Protons have a mass of 1.673x10^-24 grams and neutrons have a mass of 1.675x10^-24 grams. These are very small numbers so their weights are often given in their atomic mass units (amu), which is 1.0073amu and 1.0087amu respectively. An amu is 1.66054x10^-24 grams...
There are six major elements responsible for the majority of mass in our body (and the bodies of most living things): Hydrogen, Carbon, Nitrogen, Oxygen, Sulfur, and Phosphorous. Carbon is the building block of all (organic) life, and water (composed of H2O...
